Data supporting management of thermal springs –Steamboat Springs, Colorado
The U.S. Geological Survey (USGS), in cooperation with the city of Steamboat Springs and the Tread of Pioneers Museum, is undertaking a geologic, hydrologic, and geochemical study to better understand the sources of water to hot springs and the possible effects of land use change and human activities on the chemistry and sustainability of springs.Hydrology of an Artesian Aquifer near Manitou Springs, Colorado
The area surrounding Manitou Springs, Colorado is host to numerous bedrock springs, which help to support the local economy through tourist visitation. Although many springs previously flowed directly to the surface, most of the “springs” in the area are now more strictly classified as flowing artesian wells completed in the Manitou Formation, a cavernous intermixed limestone and dolomite, which...Hydrology of and potential for groundwater storage in the alluvial aquifer in the Wet Mountain Valley, Colorado
Hydrologic analysis of the alluvial aquifer in the Wet Mountain Valley has been undertaken using synoptic streamflow and groundwater-level elevation measurements, aquifer tests, water-quality sampling and data analysis, and numerical groundwater-flow modeling. These datasets together provide an encompassing view of the interconnected water resources in the area and allow for quantitative... - Data
Water-level and well-discharge data related to aquifer testing in Fountain Creek alluvial aquifer, El Paso County, Colorado, 2019
U.S. Geological Survey (USGS) in cooperation with the U.S. Air Force Civil Engineering Center conducted short-term aquifer tests at 11 wells to estimate hydraulic properties in the Fountain Creek alluvial aquifer, in El Paso County, Colorado. Data were collected in July 2019 over three days. Single-hole pumping and recovery tests were completed at five wells, and multiple single-hole displacementHydrologic and Geochemical Data and Models Supporting Integrated Evaluation of the Captain Jack Superfund Site, Boulder County, Colorado
The Captain Jack Superfund site near Ward, Colorado hosts extensive interconnected underground mine workings, which drain via the Big Five Adit. Drainage from the adit has historically been acidic with elevated concentrations of metals. In 2018 the U.S. Environmental Protection Agency (EPA) utilized a subsurface remediation strategy consisting of the installation of a hydraulic bulkhead within thePassive seismic (HVSR) data from Fountain Creek, CO
A total of 119 passive seismic soundings were collected with Tromino (MoHo s.r.l.) 3-axis seismometers in the Fountain Creek area to partially refine alluvial aquifer thickness (depth to bedrock) estimates, particularly over known or suspected paleochannels. Data were collected during June 21-24, 2021 with a team of 4-5 people, each equipped with a Tromino Blu or Tromino 3G passive seismometer.Water-level and pumping data, water-level models, and estimated hydraulic properties for the Paradox Valley alluvial aquifer in Montrose County, Colorado, 2013
Aquifer testing was conducted in the Paradox Valley alluvial aquifer in Montrose County, Colorado, including short-term (slug tests) and long-term (pumping tests) stresses on the hydrologic system to determine hydraulic properties of the aquifer. Slug tests were conducted at four wells in March 2013, with only one well producing data that could be interpreted using analytical solutions.

This data release contains environmental tracer concentrations, modeled recharge conditions (water temperature, excess air), and resulting estimated groundwater residence times. This dataset supports an integrated hydrogeochemical investigation of solute sources, groundwater recharge processes, and groundwater flow in the Fountain Creek alluvial aquifer. The data release contains five comma separWater-level and well-discharge data related to aquifer testing in Wet Mountain Valley, Colorado, 2019
Short-term aquifer tests were conducted to estimate hydraulic properties in an alluvial aquifer. Tests included eight single-hole pumping and recovery tests and three slug tests (in a single well). These investigations were conducted in the Wet Mountain Valley, in Custer and Fremont Counties, Colorado. The U.S. Geological Survey (USGS) conducted aquifer tests in May, 2019.

Assessing specific-capacity data and short-term aquifer testing to estimate hydraulic properties in alluvial aquifers of the Rocky Mountains, Colorado, USA
Study Region: Rocky Mountains, United StatesStudy Focus: Groundwater-flow modeling requires estimates of hydraulic properties, namely hydraulic conductivity. Hydraulic conductivity values commonly vary over orders of magnitudes however and estimation may require extensive field campaigns applying slug or pumping tests. As an alternative, specific-capacity tests can be used to estimate hydraulic prUsing an unmanned aerial vehicle water sampler to gather data in a pit-lake mining environment to assess closure and monitoring
Residual pit lakes from mining are often dangerous to sample for water quality. Thus, pit lakes may be rarely (or never) sampled. This study developed new technology in which water-sampling devices, mounted on an unmanned aerial vehicle (UAV), were used to sample three pit lakes in Nevada, USA, during 1 week in 2017. Water-quality datasets from two of the three pit lakes on public lands, Dexter anNatural and anthropogenic geochemical tracers to investigate residence times and groundwater–surface-water interactions in an urban alluvial aquifer
A multi-component geochemical dataset was collected from groundwater and surface-water bodies associated with the urban Fountain Creek alluvial aquifer, Colorado, USA, to facilitate analysis of recharge sources, geochemical interactions, and groundwater-residence times. Results indicate that groundwater can be separated into three distinct geochemical zones based on location within the flow systemNGWA Groundwater Modeling Advisory Panel Survey on the Use of Uncertainty Analysis in Groundwater Modeling
This white paper provides the results of a survey by members of the NGWA Groundwater Modeling Advisory Panel to assess the use of uncertainty analysis in groundwater modeling.The objective of the survey was to improve understanding of the use of uncertainty analysis in practical groundwater modeling projects subject to real-world constraints, such as limited budgets and tight deadlines.Non-USGS Publications**
